Wind power plant in Eastern Cape, South Africa. Approximate location -33.6763, 25.6029.
WindEastern CapeSouth Africa
Grassridge Wind Farm is a 62 MW wind power plant in Eastern Cape, South Africa. It is operated by InnoWind (Pty) Ltd Subsidiary of EDF Energies Nouvelles (EDF EN) Group. Based on its capacity (estimated), it can supply roughly 52,334 homes (estimated). It ranks #71 of 122 South Africa power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 4.7% of South Africa's electricity; the national grid averages 699 gCO₂/kWh (17.8% low-carbon) (2025).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 33.7°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 83% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 20/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
